Pulmonary Artery Aneurysm Associated with Sarcoidosis in a 75-year-old with Heart Failure: The Challenges of Diagnosis and Management.

Introduction: Pulmonary artery aneurysm (PAA) is a rare abnormality of pulmonary vasculature. It can be idiopathic or secondary to various pathologies, frequently with multiple factors leading to its formation. We report the case of a man with concomitant sarcoidosis and PAA.

Rheumatoid Arthritis and Pericardial Effusion - A Unique Major Manifestation.

Introduction: Pericardial effusion is common in the setting of rheumatoid arthritis (RA); however, it is rarely its first manifestation.

Case Description: An 82-year-old male presented with abdominal pain, vomiting and fever. Blood analysis revealed elevated systemic inflammatory markers, and an abdominal computed tomography scan revealed non-specific alveolar condensation of the right pulmonary base and pericardial effusion subsequently quantified as medium size by transthoracic echocardiography.

Portuguese Heart Failure Prevalence Observational Study (PORTHOS) rationale and design - A population-based study.

Introduction And Objectives: Current epidemiological data on heart failure (HF) in Portugal derives from studies conducted two decades ago. The main aim of this study is to determine HF prevalence in the Portuguese population. Using current standards, this manuscript aims to describe the methodology and research protocol applied.

conTemporary reflectiOns regarding heart failure manaGEmenT - How to ovERcome the PorTuguese barriers (TOGETHER-PT).

Introduction And Objectives: Heart failure (HF) is a complex clinical syndrome that is a significant burden in hospitalisations, morbidity, and mortality. Although a significant effort has been made to better understand its consequences and current barriers in its management, there are still several gaps to address. The present work aimed to identify the views of a multidisciplinary group of health care professionals on HF awareness and literacy, diagnosis, treatment and organization of care, identifying current challenges and providing insights into the future.

Triple-Valve Infective Endocarditis: A Case with Unusual Features.

Unlabelled: Infective endocarditis is a condition associated with high morbidity and mortality, usually with univalvular involvement. We describe the case of a 76-year-old woman with triple-valve endocarditis due to , complicated by perivalvular suppurative lesions, acute heart failure and acute kidney injury. Unfortunately, the patient died despite antibiotic therapy and emergent surgery.

Development and validation of a liquid chromatography method using UV/fluorescence detection for the quantitative determination of metabolites of the kynurenine pathway in human urine: Application to patients with heart failure.

Recent evidence indicates the relevant role of the tryptophan (TRP) metabolites in the pathophysiology of cardiovascular diseases via inflammatory and oxidative stress mechanisms. Therefore, quantification of TRP and its metabolites in biological samples can be a powerful tool to elucidate the disease mechanisms. The aim of this work was to develop and validate a liquid chromatography with ultraviolet (UV) and fluorescence detection (FD) (LCUV/FD) method for the quantification of TRP and its metabolites (L-kynurenine (KYN) and kynurenic acid (KA)) in urine samples from heart failure (HF) patients.

Acute Aortic Regurgitation Due to Endocarditis Caused by Disseminated Gonococcal Infection: A Case Report.

A 23-year-old man presented with cough and progressive shortness of breath. Echocardiogram showed a biscupid aortic valve with a large vegetation causing severe regurgitation. Blood cultures were positive for Neisseria gonorrhoeae sensitive to cefotaxime and penicillin.

From left ventricular ejection fraction to cardiac hemodynamics: role of echocardiography in evaluating patients with heart failure.

In clinical practice heart failure (HF) patients are generally classified on the basis of left ventricular (LV) ejection fraction. This approach, however, has important limitations. According to the definition of HF as a clinical syndrome that results from any impairment of LV filling or ejection of blood, a more articulated hemodynamic categorization of HF patients taking into account both LV forward flow and filling pressure would be desirable.

Importance of three-dimensional speckle tracking in the assessment of left atrial and ventricular dysfunction in patients with myotonic dystrophy type 1.

Introduction And Aim: Myotonic dystrophy type 1 (DM1) is a multisystem disease in which cardiac involvement is common. The aim of this study was to identify early changes in left atrial (LA) mechanics and left ventricular (LV) systolic function in patients with myotonic dystrophy type 1 using three-dimensional (3D) speckle tracking echocardiography (3D-STE).

Methods: This observational study included 25 patients with DM1 and 25 healthy volunteers.

Interpretation of B-type natriuretic peptides in the era of angiotensin receptor-neprilysin inhibitors.

Assessment of serum levels of natriuretic peptides, especially the amino-terminal portion (NT-proBNP) and the carboxy-terminal portion (BNP) of pro-B-type natriuretic peptide, has had a highly significant clinical impact on the diagnosis and prognostic stratification of patients with heart failure (HF). They are now an instrument with recognized value in this context and several studies have demonstrated their value in tailoring therapy for these patients. Following the recent advent of angiotensin receptor-neprilysin inhibitors (ARNIs), there is a need to review how these two biomarkers are interpreted in HF.

A complex case of pacemaker lead endocarditis.

Pacemaker lead endocarditis is an uncommon complication after pacemaker implantation, but is associated with high rates of morbidity and mortality. The authors describe the case of a 68-year-old woman with a double-chamber pacemaker since 2007, admitted to an internal medicine department for spondylodiscitis and Staphylococcus aureus bacteremia. During hospitalization, she had an episode of syncope; the 12-lead electrocardiogram showed pacemaker malfunction with ventricular undersensing and loss of capture.

IL-1β Inhibits Connexin 43 and Disrupts Decidualization of Human Endometrial Stromal Cells Through ERK1/2 and p38 MAP Kinase.

Inflammation can interfere with endometrial receptivity. We examined how interleukin 1β (IL-1β) affects expression of the uterine gap junction protein connexin 43 (Cx43), which is known to be critical for embryonic implantation. We used an in vitro model of human endometrial stromal cells (ESCs), Western blotting, and a combination of validated, selective kinase inhibitors to evaluate five canonical IL-1β signaling pathways.

Ischemia induced by coronary steal through a patent mammary artery side branch: a role for embolization.

Non-occlusion of the internal mammary artery side branches may cause ischemia due to flow diversion after coronary artery bypass grafting. The authors present the case of a 67-year-old man with recurrent angina after undergoing myocardial revascularization with a left internal mammary artery to left anterior descending bypass. He presented with impaired anterior wall myocardial perfusion in the setting of a patent left internal mammary artery side branch.

Complicated transcatheter closure of postinfarction ventricular acute septal defect.

The ventricular septal rupture is an uncommon complication of myocardial infarction (MI) with a reported incidence of 0.2% in the thrombolytic era. The outcome remains extremely poor, and surgical defect closure still remains the only therapeutic option improving survival.

Left main coronary artery aneurysm.

Left main coronary aneurysm is extremely uncommon and its precise pathogenesis remains poorly understood. They are associated with serious complications and treatment is still the subject of disagreement. The authors present the case of a 42-year-old man admitted for a coronary syndrome, whose coronary angiogram revealed a large left main coronary aneurysm.
